Circuit mechanisms underlying stimulus representations

What is the nature of the neural codes: how do neurons communicate with each other? What is the “language” used to represent sensory stimuli?

And how do they arise from circuit mechanisms in the brain?

We assess, in particular, how interactions between inhibitory local neurons and principal neurons of olfactory areas – be it in generating temporal patterns, filtering and selectively amplifying signals to name a few – may contribute to the computations needed to represent the external world.
